Specification of Letters Patent.

Patented June 5, 1906.

To @ZZ whom t may concern,.-

Be it knownlthat we, WILLIAM FREDERICK ELLIS, a resident of Stamford, inthe county of Fairfield and State of Connecticut, and EDWIN CURTISDAVIS, a resident of New Brunswick, in the county of Middlesex and Stateof New Jersey, citizens of the United States of America, have invented anew'and useful Tire Construction, of which the following is aspecification.

Our invention relates to improvements in tires for vehicle-wheels, andparticularly .to certain peculiar means for attaching a special kind oftire to wooden wheels, all as hereinafter set forth; and the object ofour invention is to afford a practicable and convenient constructionwhereby a tire made up of a rim and a yielding tread may be securelyfastened to a wooden felly in such a manner that saild tread can beremoved and replaced at w1 A further object of our invention is toprovide protection for the tread at the junction of its flaps with thefelly and lto inclose the fastening devices also to protect the edges ofthe rim-cover when used.

We attain these objects by the means illustrated in the accompan gdrawing, which is a cross-section of a teil-gland tire embodying ourimproved construction..

In the main our invention consists of a rim mounted on a woodenfelly,with a yielding tread mounted on said rim and having flaps `which aresecured to the'sides of the felly ly means of nails or their equivalent,guar plates being fastened to the sides of the felly also to cover andprotect the iiaps at and near their points of union with the felly. Withthese members a cover between the rim and tread is usually provided, aswill be presently explained.

An annular rim in the form of a channeliron a has its web seated on theperiphery of a wooden felly b, and said channel-iron is held in place bymeans of a radial bolt c and nut d, arranged between two of the spokes,such bolt and nut being duplicated as often as re uired around thecircumference of the whee The yielding tread here employed consists of athick flaps ff, such trea being made up in the usual manner of rubberwith =a fabricfglining,

peripheral part and side although some other suitable material ormaterials may be used, if desired. Before placing the tread e on thechannel-iron a, we generally prefer to inclose said channel-iron in acover g, of leather or other suitable material. The novel features ofour invention may or may not include the aforesaid cover, according tothe purpose for which the tire is to be employed. n

If the cover g be used, it is first drawn over the channel-iron a. Thenthe tread e is placed in osition over said cover and the iiaps f, witthe sides of the cover, are brought inward against the sides of thefelly b andthere secured by means of nails 7L, driven through the fia ls and Vcover near their edges into said fel y. Any number of nails h oneach side of the felly may be used, and screws or other equivalentdevices may be substituted for the nails.

It will be observed from the foregoing that the tread is firmly securedto the vfelly by the nails h, but that it is desirablemot to saynecessary, to cover the heads of the nails, protect the flaps f adjacentthe felly, and also rotect the edges of the cover g, assuming that thelatter be used, from the elements. To do this, we employ an annularguardlate i, preferably of sheet metal, `on each 4 side of the felly.These guard-plates are held to the sides of the felly by means of anumber of bolts passing transversely through said felly and said platesnear their inner edges and nuts, one such bolt being shown at and a nutat 7c. The lates 'i extend laterally from the sides of t e felly abovethe bolt g' and follow the outlines of the flaps f for some distancebeyond the peri hery of the felly, the adjacent portions of t e flapsand plates being 1n contlguity. The plates i not only protect the flapsand the cover at and near tneir junctions with the felly and with eachother, but cover the heads of the nails h, so that the nails cannot workout of the felly, stiffen the structure, and improve the appearancethereof.

When the tread e becomes worn out or it is desired to remove it for anyother reason, the operation of removal may be easily and quicklyperformed by releasin the guardplates f1', om their nuts and bo ts andwithdrawing lthe nails h. A new tread or cover,

IOO

' features of our invention. may be utilized in a construction Whichincludes a different kind of rim. Any suitable and equivalent substitutefor the bolts c and y' and nuts d and k may' be made and other changes,particularly in'relation to shape, size, and proportion,resorted toWithout violating the splrit of our invention.

What We claim as our invention, and desire to secure by Letters Patent,is-

,1, The combination, in tire construction, with afelly, of a channeledrim mounted on v said felly, a yielding tread mounted on said rimoverthe peripheral opening therein and havingilaps extended agalnst thesides of the felly, nails or. the like inserted in the felly afterpassingthrough said flaps, and annular guard-plates fastened to thesides ofthe felly and covering portions of the flaps beyond the felly.

2. The combination, in tire construction, With a felly, ofa channeledrim mounted on said felly, a cover extending over the peripheral openingin said rim, a yielding tread superimposed on the cover and havingflaps, said flaps and the sides of said cover extending against thesides of the felly, nails or the like inserted in the felly after assingthrough the flaps and cover, and annu ar guard-plates fastened to thesides of the felly and covering the edges of the flaps and cover andortions of the sides of the flaps beyond the fe y.-

In testimony whereof We have signed `our names to this specication inthe presence of two subscribing Witnesses.
